Specification of Letters Patent. Patented Aug. 15, 1922.

Application filed November 23,1920, Serial No. 426,097.

To all whom it mag concern: I

Be it known that We, THOMAS DrNsnN, a citizen of the United States, residing in the city, county, and State of New York, and JOHN J. Knronnn, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Display Stands, of which the following is a specification.

This invention relates to a display stand for electric lamps and has for its object to provide a device of this character possessing the various new and novel features described in the following specification, having reference to the accompanying drawings, in which Figure 1 is a front elevation of one form of display stand embodying the invention;

Figure 2 is a side view of Figure 1;

Figure 3 'is a plan view of part, of themechanism of Figures 1 and 2; Figure 4 is View showing part of the mechanism of Figure 3 in longitudinal section; c Figure 5 is a diagram showing the circuit connections employed, and

Figure 6 is a detail view showing a member of the mechanism illustrated in Figures 3. and 4. Similar characters of reference designatesimilar parts in each of the several views.

The displaystand illustrated in Figures 1 and 2 comprises a vertical frame A mounted on a table B.- The frame A comprises a pair of uprights a, a joined by a pair of horizontal members 0, 0, but it is to be understood that this is merely illustrative of one form of embodiment of the invention and that any desired form and shape of display frame may be employed. The members of the frame are preferably hollow to receive the wires of electric lamps which are mounted in sockets laced on the frame at suitable points, as illustrated, and numerals are conspicuously placed on the frame to designate the various lamps, as indicated in the drawing. It will be understood that all types and kinds of electric lamps may be placed into the sockets of the stand-and that these lamps may be changed when desired by the exhibitor.

On the table B are provided control handles 20 and 21, each of which handles is arranged to govern the circuit of the various lamps, so that by proper manipulation of of the lamps displayed on the stand.

these handles it is possible to bring about i the lightingof any desired lamp. For this purpose the handle 20 is aifixe'd to a shaft 22 (Figure 4'), which shaft extends through the casing 23 and carries a contact arm 24.

Similarly, control handle 21 is afiixed to asleeve 25 which is freeto rotate on shaft 22 and carries a contact arm-26f The above contact arms are arranged to cooperate with a number of contacts 27 (see Figure 5) and with segmental contact rings 28 and 29,the

longer contact armbeing arranged to connect the outer contact ring with the particular contact 27 'With which it is in engagement, and the shorter contact arm being arranged to provide similar connection between the said contacts and the inner contact ring 29. Contacts'27 are insulated from each other and from the rings 28 and 29 and each contact is connected to one In the diagram, however, only a few'of these contacts have been shown so connected in order to avoid confusion. The contact rings are connected in parallel with each other to one termlnal of source of current 30, a meter 31 being interposed in this connection, and one side of each of the lamps is connected to the otherterminal of the source of current 30.

In the illustrated positions ofthe-control handles 20 and 21," i

the contact arm26 completes the "circuit of the lamp 9, so that, current flows from one terminal of the source of current through meter 31, contactring 29, contact member 26 and the contact with which thefsa'me is in engagement, and lamp 9, to theothe'r terv the lamp or lamps which will meethis purpose. I

,To facilitate the selection ofthe lamps, the control handles 20 and 21 are provided with pointers 32 and 33, respectively, which cooperate with a scaleon the face ofthe casing 23, which scale, in the illustrated embodiment, consists of the numbers 1to17, inclusive, which are so spaced from each other that when a the pointer of either haniio dle is brought opposite any number, the corresponding lamp will be caused to glow. The operator may, therefore, light any lamp he desires by turning either handle until the pointer thereof coincides with the numeral corresponding to the lamp.

To give the operator information as to the costof the lamp which is illuminated. the voltage thereof, or any other desired features, the invention provides in the face of the casing 23 a pair of slots 34 and 35 with which a pair of segmental discs 36 and 37, affixed respectively to sleeve 25 and shaft 22, are arranged to cooperate. One of these discs, 36,is illustrated in Figure 6. It is made preferably of ground glass or other transparent material and is provided adjacent its rim with a scale 38 containing as many divisions as there arelamps on the stand, each division containing an inscription or legend pertaining to the lamp to which it corresponds. In the drawing, the numbers appearing in. slot 3 show that lamp 9 con sumes 15 watts and sells for forty cents. The numbers appearing in slot 35 indicate that lamp 7 consumes 60 watts and sells for forty-five cents. The customer is thus able to ascertain the wattage and cost of any of the lamps on the display stand. To enhance the clearness of the indications in slots 34: and 35, electric lamps 38 are mounted behind the segments 36 and 37.

The dial of meter 31 is calibrated preferably in terms of cost per hour for the electrical energy which is consumed by the lighted lamp. Although in the illustrated positions of the control handles the indication of'the meter gives the combined cost per hour of lamps 7 and 9, it will. be under stood that the cost ofoperating either alone may be obtained by turning the one handle beyond the scale so that the corresponding contact arm is brought beyond the ends of the contact rings and only the desired one of the lamps is lighted.

It will thus be seen that the stand of this invention serves not only to display the lamps in an attractive manner, but is provided with devices whereby the customer himself, by the mere turn of a handle, may light any desired lamp and ascertain its brilliancy of illumination, its cost, its wattage, its current consumption or operating cost and any other features with which the exhibitor desires to acquaint him. He may, moreover, light any two of the lamps simultaneously and thus compare them in actual operation.

Although only one specific form of embodiment of the invention is shown and described herein, it is to be understood that many changes and modifications may be made therein, it being intended to cover the invention broadly in whatever form its principle may be embodied.
